Abstract

The present invention is a system, apparatus, and method for a “Priority” field that is included in the information transmitted by an Access Point (AP) (801i) about its neighbor APs (801i) and the network service providers (SPs) that it supports. A “Priority” field (103i-6 154i.2 203.i.2 233 266) is included in at least one of a Neighbor Report element (100), an AP Channel Report element (150), and a service provider's information element (200 230 260). The service provider priority field (203.i.2 233 266) is contained in any protocol frame transmitted by the AP (801i) that contains information about one or more service providers that it supports. The “Priority” field (103i.6 154-i.2 203.i.2 233 266) contains a numeric value or a symbolic indicating a recommendation from the AP (801i) concerning which AP / APs and service provider(s) SP / SPs for a STA (802j) to scan first or access in an eventual roaming / accessing process. For roaming / accessing purposes, more than one neighboring AP (801i) can have the same priority value and not all the APs (801i) that are neighbors or support SPs necessarily have the same priority value.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a system, apparatus and method for prioritizing access points (APs) and / or service providers (SPs) for preferred connectivity thereto by a station (STA) in a wireless network.BACKGROUND OF THE INVENTION

[0002] The support of access to STA-selected APs is a general requirement in any wireless system where the mobile stations access the network through APs or base stations, and for many real time based applications, any delay in the access process may degrade the quality of the service. The problem of minimizing the access delay remains a major challenge for most wireless system designers. One of the main issues is the limited ability of the mobile stations in discovering and maintaining network state information for use in optimization of the AP selection procedure. This problem is compounded by the STAs' need to have information about the service providers supported by an AP and / or neighboring APs in choosing an AP to access...
